Looking over the code today I noticed that the query 'Am Falkplatz' (and friends) are relying on a
StopWordClassification
for matching.This seems brittle, this PR replaces it with the more robust
DirectionalClassification
.I've also removed
am
from the/de/stopwords.txt
file asAm Falkplatz
is a valid streetname in Germany, the preposition shouldn't be ignored.
